WebThallium is a suspected human carcinogen. Part of the reason for thallium's high toxicity is that, when present in aqueous solution as the univalent thallium (I) ion (Tl + ), it exhibits some similarities with essential alkali metal cations, particularly potassium. It can thus enter the body via potassium uptake pathways.
